Documentation: power: Add document on debugging shutdown hangs
If the kernel hangs while shutting down, ideally a UART log should
be captured to debug the problem. However if one isn't available,
users can use the pstore functionality to retrieve logs.
Add a document explaining how this works to make it more accessible
to users.
